How to Get 1000FPS Slow-Mo in Final Cut Studio (No Extra Plugins Required)

The go-to slow motion plugin in many an editor's toolbox is RE:Vision Effects' Twixtor. Twixtor can often stretch a shot originally filmed at 30 or 60 frames per second into Matrix-like levels of slowness. However, the enterprising guys at Crumblepop have come up with a way of achieving this same effect using the Optical Flow filter that ships as part of Apple Motion. Here it is in action:

Pretty mind-blowing, right? Well, in addition to the tutorial below, they also pulled another ace out of their sleeve: the rain is added in post with Trapcode Particular 2. The droplets certainly help sell the effect, though the slow-motion alone -- considering it's being re-timed from 60fps footage -- is amazing. Here's another demo:

Okay, so how did they do it? Here's the tutorial for how to achieve this effect in Apple Motion.

More about the Crumblepop guys on their own site as well as over on planet5d.

The rain during the slow section is stunning. Theres alot of hype around slow-o at the moment and its nice to see some good implimentations of it.

I thought also the rain was the most stunning looking bit of the video. And I watched it before reading the text, so I was bitterly disappointed to find out it was just a post production trick...

Is it just me, or is the Apple Motion clip not impressive at all?

It almost seems like it is as much about choosing when to cut to super slow motion (when movement is minimal, but motion is still apparent) as it is about the technology stretching and blending it all out.

Agreed, the interpolation artifacts on the bike wheels are just awful. Still nice to know the level of slo-mo you can pull off right out of the box without a plug-in.

Wow.. thanks for the tutorial link! I just got done experimenting with Twixtor on a skydiving footage taken with Canon T2i at 720P 60 fps, and could not imagine something in Motion can do something so similar.

Correction: first video was made using twixtor. It says so in the description.

that was awesome. I've seen the twixtor one before.

I'm gonna do a test and follow his steps. I'll link to it when i've done it.

Great site btw.

Is this possible with Final Cut Express, too?

No, Final Cut Express does not include Motion, which is needed for the Optical Flow filter.

Thought so.. but Twixtor is available for that one, right?

I see allot of artifacts around the wheel and shadow in the beginning that looks like Motion is not rendering correctly or just can't handle. Keep in mind, the more complex the subject moving, patterns or background, this will cause problems in the final output, situations in which Twixtor handles much better. I've tried using Motion many times for this effect and after hours of rendering and processing, usually I'm disappointed. Hopefully a new version of Motion can improve on the quality but till then, think Twixtor still reins.

Okay, the Optical Flow filter is designed for this purpose, built-in to Motion and advertised as part of the Final Cut Studio package. So how exactly did the "enterprising guys" at CrumblePop "come up with it?"

This isn't even the most efficient way to apply the Optical Flow filter, in my opinion, as any edits to it afterwords would require re-exporting. You can actually make all of your edits ahead of time in Final Cut if you'd like, including re-timing them to exactly how you want them to appear in the edit, and then export them to motion and switch the re-timing mode to Optical Flow as a final step.

That second one suffers from all the same problems as twixtor.. check the last shot when the bike is dropped on the ground and watch the front tyre. It's got that horrible warp thing going on.

Question. In the first video, how are the clouds overhead moving so quickly during the extreme slow mo sections? Is that in post as well? If that were real-time, those things would be flying through the sky like rocketships?

Right?

Does the canon 5D shoot 60fps?

Crap! Thanks anyway. Guess I'll stick to Twixtor on after effects.

There's still hope even though that was posted back in 2009.

Why not use After Effects? I've used it to create movies out of stills and its interpolation of the data seems to be far better. I've never used Twixtor or Motion before though.

Imagine a porno using Twixtor for the climax scene. That would totally take porn to the next level. Lol

There is one (kinda). It's called Behind the Green Door. It's a classic, and it's pretty hilarious. ;-)

Yeah that artifacting and warping does look pretty bad, too bad I didn't notice any of it til everybody decided to point it out, jeezus, lol...

I don't get it, Final Cut Pro X does Frame rendering/blending, so why export into Motion to do this?

hey guys. thanks for the tutorial but im having trouble. when i take my footage from final cut 6 to motion (send to motion) the clip appears in motion slowed down already, not sure if thats how its supposed to be. then when i try to change the speed to 15 percent and do the optical flow i get a ton of blur. i shot at a 2000 shutter speed 60 fps, so there shouldnt be a problem with blur, yes? i feel like my settings are wrong somewhere but i have no idea how to correct it. please help! thanks. the footage you shot looks killer.
